According to search-discovered classical Islamic scholarship, the Alms-tax, or Zakat (الزكاة), is a foundational pillar of Islam and a mandatory act of worship. Its Arabic root, meaning 'to purify' and 'to grow,' signifies its dual purpose: cleansing a Muslim's wealth and soul from avarice while fostering economic growth and social justice within the community. The Quran mentions Zakat over 30 times, often pairing it directly with prayer (Salat) to emphasize its importance. Classical authorities like Ibn Kathir and Al-Qurtubi explain that Zakat is not mere charity but a divinely ordained right of the poor over the wealth of the affluent. The specific recipients are detailed in the Quran (9:60), and the customary rate of 2.5% on surplus wealth held for a year is established in the Sunnah of the Prophet Muhammad. This systematic redistribution of wealth serves as a cornerstone of Islamic economic principles, aiming to alleviate poverty, strengthen community bonds, and serve as a practical manifestation of a believer's faith and gratitude to Allah.
